' NiTED STATES PATENT' Friet M. o. cRoNK, or AUBURN, New YORK.

IMPROVED WASHING-MACHINE.

Specification forming part of Letters Patent No. 42,352, dated April 19, 1864.

1b @ZZ whom it may concern.'

Be it known that I, M. C. CRONK, of Auburn, in the State of N ew York, have invented certain new and useful Improvements in Washing-Machines; and I hereby declare that the following is a true and exact description of' the same, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon.

The nature of my invention consists in the use of certain devices hereinafter described, to facilitate the process of washing clothes.

Figure l in the annexed drawings represents a vertical section of my machine, taken through the center. Fig. 2 represents a plan yew of the rubbers arranged at the bottom of the tub.

A in Fig. l represents the body of the tub, which is similar in form to those used for washing by hand. y

B represents a post firmly attached to the bottom of tub A and extending upward about half its length above the upper edge of A.

C represents a circular platform horizontal in position, andy extending out to within half an inch of the interior circumference of tub A. The platform C is penetrated through its center by post B, around which it is intended to play freely, and is supported by a spiral spring, e, the bottoni of the spring resting on a shoulder formed on post B.

D represents a sheath which plays on post B and rests at its lower end on platform C.'

F represents a lever with an oval-shaped hole cut through it sufficiently large to admit of its playing freely on post B.

g designates a brace, the lower end of which fits in a fork of lever F, to which it is con- Vlined by a pin, and the upper end fastened to the sleeve h, the sleeve h being made to play vertically on post B.

I represents an upright fastened at bottom vto the platform C, about midway between postB and the circumference of the tulo A, and runningparallel with B. A mortiseiscut through the long arm of lever F, through which the upright I passes. It will be observed that by this arrangement a horizontal motion is given to the platform C, as the long arm of lever F is moved in a plane parallel with the surface of the tub A. The platform C has several perforations to admit of a free passage of the water, and is furnished with a number of rubbers on its under surface. These rubbers (marked m) radiate l from near the center of platform C and are made convex on the rubbing-surface. (See Fig. 2.) The bottom of tub A is supplied with rubbers similarly constructed and arranged. By

means of the spring e, the platform C adjusts itselfto the bulk of clothing contained in the tub A.

'lhe mode of operating my machine is sim- M. C. CRONK.
